(1) To determine the effects of a 9-month resistance training intervention on quality of life, sense of coherence, and depressive symptoms in older adults, and (2) to compare effects between different training frequencies.
Men and women aged 65-75 (N = 106) were randomized to four groups according to training frequency: training groups RT1 (n = 26), RT2 (n = 27), and RT3 (n = 28) and non-training control group (n = 25). All training groups attended supervised resistance training twice a week for 3 months. For the following 6 months, they continued training with different frequencies (1, 2 or 3 times per week). Psychological functioning was measured by quality of life (WHOQOL-Bref), sense of coherence (Antonovsky's SOC-13), and depressive symptoms (Beck's Depression Inventory II). Measurements were conducted at baseline and 3 and 9 months after baseline. The effects of the intervention were analyzed using generalized estimating equations (GEE).
After 3 months, there was an intervention effect on environmental quality of life (group × time p = .048). Between 3 and 9 months, environmental quality of life decreased among RT1 compared to RT2 and RT3 (group × time p = .025). Between baseline and 9 months, environmental quality of life increased in RT2 compared to all other groups (group × time p = .011). Sense of coherence increased in RT2 compared to the control group and RT3 (group × time p = .032).
Resistance training is beneficial for environmental quality of life and sense of coherence. Attending resistance training twice a week seems to be the most advantageous for these aspects of psychological functioning.
（1）确定为期 9 个月的抗阻训练干预对老年人生活质量、心理一致感和抑郁症状的影响，（2）比较不同训练频率的效果。
根据训练频率将 65-75 岁的男性和女性（N=106）随机分为 4 组：训练组 RT1（n=26）、RT2（n=27）、RT3（n=28）和非训练对照组（n=25）。所有训练组每周接受 2 次监督抗阻训练，持续 3 个月。接下来的 6 个月，他们以不同的频率（每周 1、2 或 3 次）继续训练。心理功能通过生活质量（WHOQOL-Bref）、心理一致感（Antonovsky 的 SOC-13）和抑郁症状（Beck 抑郁量表 II）进行测量。在基线和基线后 3 个月和 9 个月进行测量。使用广义估计方程（GEE）分析干预效果。
3 个月后，生活环境质量存在干预效应（组×时间 p=0.048）。在 3 至 9 个月期间，与 RT2 和 RT3 相比，RT1 的环境生活质量下降（组×时间 p=0.025）。在基线和 9 个月之间，RT2 的环境生活质量比所有其他组都有所增加（组×时间 p=0.011）。与对照组和 RT3 相比，RT2 的心理一致感增加（组×时间 p=0.032）。
抗阻训练有利于环境生活质量和心理一致感。每周参加 2 次抗阻训练似乎对这些心理功能方面最有利。
